Simulation of the Realistic Dynamic Behaviour of Aircrafts


flying different engine powered aircrafts,

flying a glider with winch start and with thermic,

flying a RC(remote controlled)aircraft model as a pilot fixed to the ground ,

creating aircrafts in different configurations and testing their characteristics in flight,

flying Air Race

If you are interested in any of these features you can Download FDS and test it.


The FDS-Technology uses Physical Laws as much as possible. This means

. solution of the six equations of motion for the six degrees of freedom,

calculation of the aerodynamic forces for the aircraft parts(wing, fuselage, rudder, elevator, landing gears, etc.) with analytic equations and parameters from wind tunnel experiments,

calculation of the propeller thrust with analytic equations,

calculation of the jet engine thrust with solving the gas turbine process with/without bypass and with/without afterburner,

calculation of the gear forces as a spring/damper system and of the wheel forces with analytic equations,

configuration of the aircraft parameters in a user friendly GUI (Graphical User Interface).

The GUI-GraphicUserInterface is build withTcl/TK.

In order to present the aircraft's geometry, the 3D-modeller AC3D from Andy Colebourne is used.

The code is written in C-language and uses for the graphics implementation the library PLIB, which layers on top of 10

As an interface to audio hardware the three-dimensional audio API


is used.

The minimum requirements are a Windows98/ME/NT/2000/XP-PC with 166 Mhz processor, 64 Mb ram, a four axis joystick and 16 Mb 3D-graphics card with OpenGL driver (must be installed on your PC) for hardware acceleration.
